Yes, easily. However, if McTominay was playing in midfield in a 3-5-2, Jack would more likely have played as the left player of a central three and no one would have batted an eyelid i.e. McTominay, McGinn, Jack. McGinn being further forward than the defensive pairing. So now it’s McTominay, McGinn, Tierney.
We need someone in there who will put pressure on the ball like Jack does, and it can’t be Callum McGregor.
